Placing double chest and moving it with a sticky piston the chest will break into two normal chests and the nearest chest to the sticky piston will go back with the piston but the far one will stand still on its own i know that new piston have the ability to move chests but am checking if moving two chest and got broken is a bug

AMAN4700: When you retract a sticky piston the chest doesn't connect back together leaving two single chests.
